Cisco ASA Series CLI Configuration Guide
Chapter 1 Managing Feature Licenses
Configuring Licenses
• On a single unit, you cannot add two separate licenses for the same feature together; for example, if
you purchase a 25-session SSL VPN license, and later purchase a 50-session license, you cannot use
75 sessions; you can use a maximum of 50 sessions. (You may be able to purchase a larger license
at an upgrade price, for example from 25 sessions to 75 sessions; this kind of upgrade should be
distinguished from adding two separate licenses together).
• Although you can activate all license types, some features are incompatible with each other. In the
case of the AnyConnect Essentials license, the license is incompatible with the following licenses:
AnyConnect Premium license, shared AnyConnect Premium license, and Advanced Endpoint
Assessment license. By default, the AnyConnect Essentials license is used instead of the above
licenses, but you can disable the AnyConnect Essentials license in the configuration to restore use
of the other licenses using the no anyconnect-essentials command.
Configuring Licenses
This section includes the following topics:
• Obtaining an Activation Key, page 1-35
• Activating or Deactivating Keys, page 1-36
• Configuring a Shared License, page 1-37
Obtaining an Activation Key
To obtain an activation key, you need a Product Authorization Key, which you can purchase from your
Cisco account representative. You need to purchase a separate Product Activation Key for each feature
license. For example, if you have the Base License, you can purchase separate keys for Advanced
Endpoint Assessment and for additional AnyConnect Premium sessions.
After obtaining the Product Authorization Keys, register them on Cisco.com by performing the
following steps.
Detailed Steps
Step 1 Obtain the serial number for your ASA by entering the following command.
hostname# show activation-key
Step 2 If you are not already registered with Cisco.com, create an account.
Step 3 Go to the following licensing website:
http://www.cisco.com/go/license
Step 4 Enter the following information, when prompted:
• Product Authorization Key (if you have multiple keys, enter one of the keys first. You have to enter
each key as a separate process.)
• The serial number of your ASA
• Your e-mail address
An activation key is automatically generated and sent to the e-mail address that you provide. This key
includes all features you have registered so far for permanent licenses. For time-based licenses, each
license has a separate activation key.
